said by AnonShawUser:Yes, but if enough people do try to do it, they can't honestly say there's no demand.
And many of the ISPs use the clause that it's not for -commercial- servers, or for distribution of copyright material. Which would indeed make such a server 100% legit, by the TOS.
Many ISPs have self-serving data collection methods that will allow them to not acknowledge the demand no matter how many people request the speed or violate the TOS by running servers to prove their need for the speed. When there is a problem with the network, they always claim that yours is the first report even though lots of people are reporting it (ie: The data collection that ignores issues that the ISP does not want to acknowledge). OTOH: Banning customers for running Servers in violation of the TOS will affect the bottom line so it may get some attention.
